J1. Data Quality Indicators

Specific data quality indicator (DQI) limits for the Stage 5 EA works were adopted in accordance with the ASC NEPM (NEPC 2013) and standard JBS&G procedures for field sampling and handling.

To assess the usability of the data prior to making decisions, the data was assessed against appropriate DQIs established in relation to precision, accuracy, representativeness, comparability and completeness and sensitivity (PARCCS parameters), as follows:

• Precision – measures the reproducibility of measurements under a given set of conditions. The precision of the laboratory data and sampling techniques is assessed by calculating the Relative Percent Difference (RPD) of duplicate samples;

• Accuracy – measures the bias in a measurement system. The accuracy of the laboratory data that are generated during this study is a measure of the closeness of the analytical results obtained by a method to the ‘true’ value. Accuracy is assessed by reference to the analytical results of laboratory control samples, laboratory spikes and analyses against reference standards;

• Representativeness – expresses the degree which sample data accurately and precisely represent a characteristic of a population or an environmental condition. Representativeness is achieved by collecting samples on a representative basis across the site, and by using an adequate number of sample locations to characterise the site to the required accuracy;

• Comparability – expresses the confidence with which one data set can be compared with another. This is achieved through maintaining a level of consistency in techniques used to collect samples, ensuring analysing laboratories use consistent analysis techniques and reporting methods;

• Completeness – is defined as the percentage of measurements made which are judged to be valid measurements. The completeness goal is set at there being sufficient valid data generated during the study; and

• Sensitivity – expresses the appropriateness of the chosen laboratory methods, including the limits of reporting.

The DQIs adopted as part of the assessment are summarised in Table J1.1.

J2. Groundwater

Table J2.1 summarises the quality assurance (QA) and quality control (QC) activities undertaken to ensure integrity of the groundwater data collected and conformance with the DQIs outlined in Section J1. Any departures from the DQIs are noted in Table J2.1.

Table J2.1: Groundwater QA/QC Program

QA/QC Item Detail

QA

Field Procedures Field procedures were undertaken in accordance with relevant guidelines outlined in Section 6.

Decontamination of Equipment All drilling equipment used during the installation of groundwater wells (MW38-MW43) was decontaminated prior to the commencement of drilling at each location with phosphate free detergent followed by rinsing with deionised water. Rinsate samples were collected on every day of groundwater well drilling / installation works to validate the decontamination process.

All low-density polyethylene (LDPE) tubing and footvalves used during the development of wells was dedicated to a specific well.

All LDPE twin tubing used during the sampling of wells were dedicated to a specific well. The IP, low flow pump and water quality meter were used for all wells sampled and hence were decontaminated prior to the commencement of sampling at each groundwater well with phosphate free detergent followed by rinsing with deionised water. Rinsate samples were collected on every day of groundwater sampling to validate the decontamination process.

Laboratories used and NATA accreditation

Eurofins MGT (primary laboratory) and Envirolab (secondary laboratory for QC purposes) are NATA accredited for the analyses undertaken.

©JBS&G Australia Pty Ltd | 54089-111775 RP02 (Rev0) App J-iii

QA/QC Item Detail

Sample Tracking COC documentation was used for the transport of all samples to the laboratory and is included in Appendix K (along with the laboratory certificates of analysis).

Sample Preservation and Storage Samples were collected in laboratory supplied bottles with specific preservation for the chemicals of interest, and were kept in a chilled insulated box and transported to the laboratory.

Holding Times Samples were analysed within specified holding times by both the primary and secondary laboratory.

Data Transcription Summary results tables are appended to this report, which were generated from laboratory supplied ESdat files, minimising the potential for transcription errors.

Laboratory Limits of Reporting (LORs)

The LORs are presented in the groundwater laboratory certificates of analysis (Appendix K) and included in the Summary Tables.

The LORs outlined in the DQIs were achieved with the exception of the required LOR for VC for 7 primary samples (MW12, MW36, MW37, MW39-MW41 and MW43). It is noted ultra-trace analysis was undertaken for all chlorinated hydrocarbons (including VC), however, the LORs were raised due to matrix interference for some samples which resulted in VC having an LOR above the adopted screening level in some samples.

QC

Intra-laboratory Duplicate Samples One intra-laboratory duplicate sample was collected during the groundwater monitoring program. This frequency was in accordance with the DQIs. The following intra-laboratory duplicate sample pair was collected:

• ‘DUP01’ was collected with primary sample ‘MW37’ on 29 September 2017. Both samples were analysed for CEs.

A total of six RPD values were calculated. All RPD results were within the acceptable range (0 % to 30%) outlined in the DQIs.

The groundwater intra-laboratory duplicate sample pair results and RPD values have been summarised in the Summary Tables.

Inter-laboratory Duplicate Samples One inter-laboratory duplicate sample was collected during the groundwater monitoring program. This frequency was in accordance with the DQIs. The following inter-laboratory duplicate sample pair was collected:

• ‘SPLIT01’ was collected with primary sample ‘MW37’ on 29 September 2017. Both samples were analysed for CEs.

A total of six RPD values were calculated. All RPD results were within the acceptable range (0 % to 30%) outlined in the DQIs.

The groundwater inter-laboratory duplicate sample pair results and RPD values have been summarised in the Summary Tables.

Rinsate Blank Samples Groundwater Well Installation

Rinsate samples were collected on every day of groundwater well installation works in order to validate the decontamination procedures undertaken for the drilling equipment. This frequency was in accordance with the DQIs.

Three rinsate samples were collected during the installation of groundwater wells, as follows:

• ‘RB01’ on 21 September 2017;

• ‘RB02’ on 22 September 2017; and

• ‘RB03’ on 25 September 2017.

All rinsate samples were collected by running deionised water over the clean lead auger head. All rinsate samples were analysed for CEs. All results were below laboratory reporting limits, as required by the DQIs.

Groundwater Well Sampling

QA/QC Item Detail

Two rinsate samples were collected during the groundwater sampling program, as follows:


• ‘RB05’ on 3 October 2017.

All rinsate samples were collected by running deionised water through the clean low flow pump. All rinsate samples were analysed for CEs. All results were below laboratory reporting limits, as required by the DQIs.

The results of the rinsate samples are summarised in the Summary Tables and included in the laboratory certificates of analysis in Appendix K.

Trip Blank Samples One trip blank sample (‘TRIPBLANK01’) was transported to and from site, and treated in the same manner as the groundwater samples collected on 3 and 4 October 2017 (MW12, MW24, MW36 and MW38-MW43) to ensure samples were not impacted during transport. It is noted a trip blank sample was not transported with the samples collected on 29 September 2017 (primary sample MW37 and duplicate samples) and hence the frequency of trip blank samples was not in accordance with the DQIs. Given the consistent sampling and transportation procedures implemented, this is not considered to impact on the outcomes of the investigation. In addition, it is noted the Stage 5 EA Works results for MW37 were similar (within 30 %) to the Stage 4 EA Works results for all chemicals.

The trip blank sample was analysed for CEs. All results were below laboratory reporting limits, as required by the DQIs.

The results of the trip blank sample are included summarised in the Summary Tables and included in the laboratory certificates of analysis in Appendix K.

Trip Spike Samples One trip spike sample (‘TRIPSPIKE01’) was transported to and from site, and treated in the same manner as the groundwater samples collected on 3 and 4 October 2017 (MW12, MW24, MW36 and MW38-MW43) to ensure there was no significant loss of volatiles during transport. It is noted a trip spike sample was not transported with the samples collected on 29 September 2017 (primary sample MW37 and duplicate samples) and hence the frequency of trip spike samples was not in accordance with the DQIs. Given the consistent sampling and transportation procedures implemented, this is not considered to impact on the outcomes of the investigation. In addition, it is noted the Stage 5 EA Works results for MW37 were similar (within 30 %) to the Stage 4 EA Works results for all chemicals.

The trip spike sample was pre-dosed with, and analysed for, benzene, toluene, ethylbenzene and xylenes (BTEX). The trip spike sample recoveries ranged between 77 % and 95 %, indicating no significant loss of volatiles during transport – this is within the acceptable range of 70 % to 130 % outlined in the DQIs. It is noted the trip spike samples were in transit for twice as long as the groundwater samples and hence any loss reported in the trip spike sample is likely to be greater than that of the groundwater samples.

The results of the trip spike sample are included summarised in the Summary Tables and included in the laboratory certificates of analysis in Appendix K.

Laboratory Internal QC Eurofins MGT (primary laboratory) and Envirolab (secondary laboratory for QC purposes) undertook internal QA procedures and internal QC testing, including laboratory blank samples (both laboratories), spike samples (both laboratories) and laboratory duplicate samples (Eurofins MGT only). The following was noted:

• Laboratory blank samples: All results were below the laboratory reporting limits;

• Spike samples: The recoveries from the laboratory control spike samples were within the specified range for each chemical; and

• Laboratory duplicate samples: The RPD values reported for all internal duplicate pairs were within the acceptable range outlined within the ASC NEPM (NEPC 2013).

J3. Soil Vapour

Table J3.1 summarises the QA and QC activities undertaken to ensure integrity of the soil vapour data collected and conformance with the DQIs outlined in Section J1. Any departures from the DQIs are noted in Table J3.1.

Field Procedures Field procedures were undertaken in accordance with the references in Section 7.

Decontamination of Equipment All drilling equipment used during the installation of soil vapour probes (VP67-VP72) was decontaminated prior to the commencement of drilling at each location with phosphate free detergent followed by rinsing with deionised water. Rinsate samples were collected on every day of soil vapour probe drilling / installation works to validate the decontamination process.

Dedicated soil vapour sampling equipment was used at each sampling location.


Envirolab (primary laboratory) and ALS (secondary laboratory for QC purposes) are NATA accredited for the analyses undertaken.

Sample Tracking COC documentation was used for the transport of all samples to the laboratory.

Sample Preservation and Storage Summa canisters were stored in laboratory supplied pelican cases and transported to the laboratory.


Laboratory Detection Limits The LORs are presented in the soil vapour laboratory certificates of analysis (Appendix N) and included in the Summary Tables.

The required LORs outlined in the DQIs were achieved with the exception of the following:

• PCE – two primary samples (VP71 and VP72);

• TCE – two primary samples (VP71 and VP72);

• cis-1,2-DCE – 7 primary samples (VP44, VP66 and VP68-VP72);

• trans-1,2-DCE – 7 primary samples (VP44, VP66 and VP68-VP72);

• 1,1-DCE – three primary samples (VP70-VP72); and

• VC – 9 primary samples (VP18, VP29, VP44, VP66 and VP68-VP72).

The LORs in VP18, VP29, VP44, VP66 and VP68-VP71 were raised due the presence of elevated concentrations of other CEs (except the LOR for isopropanol in VP18 and the LORs for CEs in VP71 which were raised due to the presence of elevated concentrations of analytes other than those being tested). With the exception of VP71 (discussed further below), the raised LORs in these soil vapour probes are not considered to impact on the conclusions of this report as the LOR outlined in the DQIs for the key chemical driving risk at the site (TCE) was achieved.

The LORs in VP72 were raised due to the lower volume of available sample – a lower sample volume was obtained for this soil vapour probe due to low vapour yield despite an increased sampling time.

Further consideration should be given to the potential for elevated CE vapour concentrations (particularly the key chemical driving risk at the site [TCE)]) to be present at VP71 and VP72, particularly when assessing delineation of the soil vapour plume. However, it should be noted TCE concentrations at these locations were below 80 µg/m3 (the LOR for the samples) which is significantly lower than the highest TCE concentration reported during the September 2017 soil vapour monitoring event (18,000 µg/m3 at VP29) and hence these elevated LORs for these samples are not considered to impact on the conclusions of this report regarding risks to human health.

QA/QC Item Detail

QC

Rinsate Blank Samples As outlined above, rinsate samples were collected on every day of soil vapour probe installation works to validate the decontamination procedures undertaken for the drilling equipment. This frequency was in accordance with that outlined in the DQIs.

Three rinsate samples were collected during the installation of soil vapour probes, as follows:

• ‘RB01’ on 21 September 2017;


• ‘RB03’ on 25 September 2017.

All rinsate samples were collected by running deionised water over the clean lead auger head. All rinsate samples were analysed for CEs. All results were below laboratory reporting limits, as required by the DQIs.

The results of the rinsate samples are summarised in the Summary Tables and included in Laboratory Certificates of Analysis in Appendix K.

Certification of Summa Canisters All Summa canisters were certified as clean by the primary laboratory (Envirolab) prior to dispatch, with all Summa canisters provided returning results for all VOCs below the LOR.

Integrity Testing – Helium Leak Test All soil vapour probes passed the helium leak test, given the concentration reported in the soil vapour probes was below 10 % of that reported in the shroud, as required by the DQIs. This indicates adequate soil vapour probe construction.

Helium leak test results are included in the Summary Tables.

Integrity Testing – Isopropanol Leak Test

One shroud sample (‘SHROUD01’) was collected during the soil vapour monitoring event and analysed for isopropanol. An isopropanol concentration of 1,300,000 µg/m3 was reported in the shroud sample.

The concentration of isopropanol within the soil vapour samples was compared to the acceptable concentration outlined in the DQIs (10 % of that reported in the shroud sample – 130,000 µg/m3). All soil vapour samples reported isopropanol concentrations below this acceptable concentration and hence passed the isopropanol leak test, indicating acceptable ingress of ambient air during sampling.

Isopropanol leak test results are included in the Summary Tables.

Receipt Pressure of Samples The pre- and post-sampling pressure, and the final pressure of the passivated (Summa Canister Samples) canisters on receipt at the laboratory are summarised in the Summary Tables.

The pre-sampling pressure was -30 inHg for all canisters used in the soil vapour sampling, indicating negligible loss of pressure between shipping from the laboratory to receipt for sampling. The post-sampling pressure was compared to the final laboratory receipt pressure, with the difference below 1 inHg for all soil vapour samples (below the maximum of 5 inHg outlined in the DQIs).

The results indicate little loss of pressure and low potential for ambient air ingress during transit for all summa canister samples.

Intra-Laboratory Duplicate Samples One intra-laboratory duplicate sample pair was collected and analysed as part of the soil vapour monitoring program for a total of 11 primary samples. This frequency is in accordance with the required frequency outlined in the DQIs. The following intra-laboratory duplicate sample was collected:

• ‘DUP01’ was collected with primary sample ‘VP70’ on 27 September 2017.

The intra-laboratory duplicate sample pair was analysed for the chemicals of interest (CEs). A total of six RPD values were calculated – all RPDs were within the acceptable range (0 % to 30 %) outlined in the DQIs.

The soil vapour intra-laboratory duplicate sample pair results and RPD values have been summarised in the Summary Tables. Laboratory results are included in Laboratory Certificates of Analysis in Appendix N.

Inter-Laboratory Duplicate Samples One inter-laboratory duplicate sample pair was collected and analysed as part of the soil vapour monitoring program for a total of 11 primary samples. This frequency is

in accordance with the required frequency outlined in the DQIs. The following inter-laboratory duplicate sample was collected:

• ‘DUP02’ was collected with primary sample ‘VP67’ on 27 September 2017.

The inter-laboratory duplicate sample pair was analysed for the chemicals of interest (CEs). A total of six RPD values were calculated – all RPDs were within the acceptable range (0 % to 30%) outlined in the DQIs.

The soil vapour inter-laboratory duplicate sample pair results and RPD values have been summarised in the Summary Tables. Laboratory results are included in Laboratory Certificates of Analysis in Appendix N.

Laboratory Internal QC Envirolab (primary laboratory) and ALS (secondary laboratory for QC purposes) undertook internal QA procedures and internal QC testing, including:

• Laboratory blank samples - All results were below the laboratory reporting limits.

• Duplicate samples - The RPD values reported for all internal duplicate pairs within the acceptable range; and

• Spike samples - The recoveries from the laboratory control spike samples were within the specified range for each chemical.

QC

Intra-Laboratory Duplicate Samples One intra-laboratory duplicate sample pair was collected and analysed as part of the service pit monitoring program for a total of 10 primary samples. This frequency is in accordance with the required frequency outlined in the DQIs. The following intra-laboratory duplicate sample was collected:

• ‘DUP_SP01’ was collected with primary sample ‘SP01’ on 4 October 2017.

The intra-laboratory duplicate sample pair was analysed for the chemicals of interest (CEs). A total of 6 RPD values were calculated – all RPDs were within the acceptable range (0 % to 30 %) outlined in the DQIs with the exception of that for PCE which slightly exceeded the acceptable range (33 %). This elevated RPD is attributed to the low concentrations reported in these samples (2.5 µg/m3 for SP01; 3.5 µg/m3 for DUP_SP01). The higher PCE concentration was reported in the

duplicate sample and this concentration has been adopted in the assessment of results.

The service pit intra-laboratory duplicate sample pair results and RPD values have been summarised in the Summary Tables. Laboratory results are included in Laboratory Certificates of Analysis in Appendix P.

Inter-Laboratory Duplicate Samples One inter-laboratory duplicate sample pair was collected and analysed as part of the service pit monitoring program for a total of 10 primary samples. This frequency is in accordance with the required frequency outlined in the DQIs. The following inter-laboratory duplicate sample was collected:

• ‘DUP_SP02’ was collected with primary sample ‘SP02’ on 4 October 2017.

The inter-laboratory duplicate sample pair was analysed for PCE and TCE. A total of two RPD values were calculated – both RPDs exceeded the acceptable range (0 % to 30 %) outlined in the DQIs, with significantly higher concentrations reported for both chemicals in the primary sample, as follows:

• PCE (RPD of 155 %): 19 µg/m3 in SP02; 2.41 µg/m3 in DUP_SP02; and

• TCE (RPD of 128 %): 19 µg/m3 in SP02; 4.15 µg/m3 in DUP_SP02.

These results were reviewed and it was considered that the discrepancy was between the total concentrations (in ng/tube) reported by the laboratories for the samples (i.e. calculation of concentration in µg/m3 had been completed correctly as based on sampling time).

Both laboratories were contacted regarding these results (correspondence is included in Appendix T). The following was noted:

• Envirolab (primary laboratory): The results were reviewed by the analyst – no errors were identified and the QC was appropriate. The laboratory noted these results were above the calibration range (i.e. the results may be higher than those reported); and

• ALS (secondary laboratory for QC purposes): The results were reviewed by the analyst – no errors were identified and the QC was appropriate. The sample was re-analysed, and results of the second analysis confirmed the initial results.

Based on the above, analytical procedure does not appear to be the cause of the discrepancy in results between the two laboratories. There is a possibility the difference in the concentrations may be attributed to potential issues with the diffusive body used for sampling (i.e. blockages etc), however, no visible abnormalities were observed during sampling. The higher PCE and TCE concentrations reported (those in the primary sample) have been adopted in the assessment of results.

The service pit inter-laboratory duplicate sample pair results and RPD values have been summarised in the Summary Tables. Laboratory results are included in Laboratory Certificates of Analysis in Appendix P.

Trip Blank Samples (Radiello Samples)

One trip blank Radiello sample (‘Blank 01’) was collected as part of the service pit monitoring program for a total of 10 primary service pit samples. This frequency is in accordance with the frequency outlined in the DQIs.

The trip blank Radiello sample was transported to and from site and treated in the same manner as the primary samples in order to ensure elevated concentrations of the chemicals of interest (PCE, TCE, cis-1,2-DCE, trans-1,2-DCE, 1,1-DCE and VC) were not introduced during transport.

All trip blank Radiello samples were analysed for the chemicals of interest (PCE, TCE, cis-1,2-DCE, trans-1,2-DCE, 1,1-DCE and VC). All results were below laboratory reporting limits, as required by the DQIs.

The results of the trip blank Radiello samples are summarised in the Summary Tables and included in Laboratory Certificates of Analysis in Appendix P.

Certification of Summa Canisters All Summa canisters were certified as clean by the primary laboratory (Envirolab) prior to dispatch, with all Summa canisters provided returning results for all VOCs below the LOR.

Integrity Testing – Helium Leak Test All soil vapour probes passed the helium leak test, given the concentration reported in the crawlspace sample train was below 10 % of that reported in the shroud, as required by the DQIs. This indicates adequate crawlspace sample setup.

Helium leak test results are included in the Summary Tables.

Receipt Pressure of Samples (Summa Canister Samples)

The pre- and post-sampling pressure, and the final pressure of the Summa canisters on receipt at the laboratory are summarised in the Summary Tables.

The pre-sampling pressure was -30 inHg for all canisters used in the crawlspace sampling, indicating negligible loss of pressure between shipping from the laboratory to receipt for sampling. The post-sampling pressure was compared to the final laboratory receipt pressure, with the difference below 1 inHg for all crawlspace samples (below the maximum of 5 inHg outlined in the DQIs).

The results indicate little loss of pressure and low potential for ambient air ingress during transit for all crawlspace samples.

Intra-Laboratory Duplicate Samples One intra-laboratory duplicate sample pair was collected and analysed as part of the crawlspace monitoring program for a total of three primary samples. This frequency is in accordance with the required frequency outlined in the DQIs. The following intra-laboratory duplicate sample was collected:

Sample HistoryWhere samples are submitted/analysed over several days, the last date of extraction and analysis is reported.A recent review of our LIMS has resulted in the correction or clarification of some method identifications. Due to this, some of the method reference information on reports has changed. However,no substantive change has been made to our laboratory methods, and as such there is no change in the validity of current or previous results (regarding both quality and NATA accreditation).

If the date and time of sampling are not provided, the Laboratory will not be responsible for compromised results should testing be performed outside the recommended holding time.

QC - Acceptance Criteria

QC Data General Comments

1. Laboratory QC results for Method Blanks, Duplicates, Matrix Spikes, and Laboratory Control Samples are included in this QC report where applicable. Additional QC data may be available on

request.

2. All soil results are reported on a dry basis, unless otherwise stated.

3. All biota results are reported on a wet weight basis on the edible portion, unless otherwise stated.

4. Actual LORs are matrix dependant. Quoted LORs may be raised where sample extracts are diluted due to interferences.

5. Results are uncorrected for matrix spikes or surrogate recoveries except for PFAS compounds.

6. SVOC analysis on waters are performed on homogenised, unfiltered samples, unless noted otherwise.

7. Samples were analysed on an 'as received' basis.

8. This report replaces any interim results previously issued.

Please refer to 'Sample Preservation and Container Guide' for holding times (QS3001).

For samples received on the last day of holding time, notification of testing requirements should have been received at least 6 hours prior to sample receipt deadlines as stated on the Sample

Receipt Advice.

If the Laboratory did not receive the information in the required timeframe, and regardless of any other integrity issues, suitably qualified results may still be reported.

Holding times apply from the date of sampling, therefore compliance to these may be outside the laboratory's control.

**NOTE: pH duplicates are reported as a range NOT as RPD

mg/kg: milligrams per kilogram mg/L: milligrams per litre

ug/L: micrograms per litre ppm: Parts per million

ppb: Parts per billion %: Percentage

org/100mL: Organisms per 100 millilitres NTU: Nephelometric Turbidity Units

MPN/100mL: Most Probable Number of organisms per 100 millilitres

Dry Where a moisture has been determined on a solid sample the result is expressed on a dry basis.

LOR Limit of Reporting.

SPIKE Addition of the analyte to the sample and reported as percentage recovery.

RPD Relative Percent Difference between two Duplicate pieces of analysis.

LCS Laboratory Control Sample - reported as percent recovery.

CRM Certified Reference Material - reported as percent recovery.

Method Blank In the case of solid samples these are performed on laboratory certified clean sands and in the case of water samples these are performed on de-ionised water.

Surr - Surrogate The addition of a like compound to the analyte target and reported as percentage recovery.

Duplicate A second piece of analysis from the same sample and reported in the same units as the result to show comparison.

APHA American Public Health Association

TCLP Toxicity Characteristic Leaching Procedure

COC Chain of Custody

SRA Sample Receipt Advice

QSM Quality Systems Manual ver 5.1 US Department of Defense

CP Client Parent - QC was performed on samples pertaining to this report

NCP Non-Client Parent - QC performed on samples not pertaining to this report, QC is representative of the sequence or batch that client samples were analysed within.

TEQ Toxic Equivalency Quotient

RPD Duplicates: Global RPD Duplicates Acceptance Criteria is 30% however the following acceptance guidelines are equally applicable:

Results <10 times the LOR : No Limit

Results between 10-20 times the LOR : RPD must lie between 0-50%

Results >20 times the LOR : RPD must lie between 0-30%

Surrogate Recoveries: Recoveries must lie between 50-150%-Phenols & PFASs

PFAS field samples that contain surrogate recoveries in excess of the QC limit designated in QSM 5.1 where no positive PFAS results have been reported have been reviewed and no data was

affected.

1. Where a result is reported as a less than (<), higher than the nominated LOR, this is due to either matrix interference, extract dilution required due to interferences or contaminant levels within

the sample, high moisture content or insufficient sample provided.

2. Duplicate data shown within this report that states the word "BATCH" is a Batch Duplicate from outside of your sample batch, but within the laboratory sample batch at a 1:10 ratio. The Parent

and Duplicate data shown is not data from your samples.

3. Organochlorine Pesticide analysis - where reporting LCS data, Toxaphene & Chlordane are not added to the LCS.

4. Organochlorine Pesticide analysis - where reporting Spike data, Toxaphene is not added to the Spike.

5. Total Recoverable Hydrocarbons - where reporting Spike & LCS data, a single spike of commercial Hydrocarbon products in the range of C12-C30 is added and it's Total Recovery is reported

in the C10-C14 cell of the Report.

6. pH and Free Chlorine analysed in the laboratory - Analysis on this test must begin within 30 minutes of sampling.Therefore laboratory analysis is unlikely to be completed within holding time.

Analysis will begin as soon as possible after sample receipt.

7. Recovery Data (Spikes & Surrogates) - where chromatographic interference does not allow the determination of Recovery the term "INT" appears against that analyte.

8. Polychlorinated Biphenyls are spiked only using Aroclor 1260 in Matrix Spikes and LCS.

9. For Matrix Spikes and LCS results a dash " -" in the report means that the specific analyte was not added to the QC sample.

10. Duplicate RPDs are calculated from raw analytical data thus it is possible to have two sets of data.

Report Comments:

VCH: PQL has been raised due to the high concentration of analytes in the sample/s, resulting

in the sample/s requiring dilution.

Asbestos ID was analysed by Approved Identifier: Not applicable for this job

Asbestos ID was authorised by Approved Signatory: Not applicable for this job

INS: Insufficient sample for this test PQL: Practical Quantitation Limit NT: Not tested

NR: Test not required RPD: Relative Percent Difference NA: Test not required

<: Less than >: Greater than LCS: Laboratory Control Sample


Revision No: R 00


Quality Control Definitions

Blank: This is the component of the analytical signal which is not derived from the sample but from reagents,

glassware etc, can be determined by processing solvents and reagents in exactly the same manner as for samples.

Duplicate : This is the complete duplicate analysis of a sample from the process batch. If possible, the sample

selected should be one where the analyte concentration is easily measurable.

Matrix Spike : A portion of the sample is spiked with a known concentration of target analyte. The purpose of the matrix

spike is to monitor the performance of the analytical method used and to determine whether matrix interferences exist.

LCS (Laboratory Control Sample) : This comprises either a standard reference material or a control matrix (such as a blank

sand or water) fortified with analytes representative of the analyte class. It is simply a check sample.

Surrogate Spike: Surrogates are known additions to each sample, blank, matrix spike and LCS in a batch, of compounds

which are similar to the analyte of interest, however are not expected to be found in real samples.

Laboratory Acceptance Criteria

Duplicate sample and matrix spike recoveries may not be reported on smaller jobs, however, were analysed at a frequency

to meet or exceed NEPM requirements. All samples are tested in batched of 20. The duplicate sample RPD and matrix

spike recoveries for the batch were within the laboratory acceptance criteria.

Filters, swabs, wipes, tubes and badges will not have duplicate data as the whole sample is

generally extracted during sample extraction.

Spikes for Physical and Aggregate Tests are not applicable.

For VOCs in water samples, three vials are required for duplicate or spike analysis.

Duplicates: <5xPQL - any RPD is acceptable; >5xPQL - 0-50% RPD is acceptable.

Matrix Spikes, LCS and Surrogate recoveries: Generally 70-130% for inorganics/metals; 60-140%

for organics (+/-50% surrogates) and 10-140% for labile SVOCs (including labile surrogates),

ultra trace organics and speciated phenols is acceptable.

In circumstances where no duplicate and/or sample spike has been

reported at 1 in 10 and/or 1 in 20 samples respectively, the sample

volume submitted was insufficient in order to satisfy

laboratory QA/QC protocols.

When samples are received where certain analytes are outside of

recommended technical holding times (THTs), the analysis has

proceeded. Where analytes are on the verge of breaching THTs,

every effort will be made to analyse within the THT or as

soon as practicable.

Where sampling dates are not provided, Envirolab are not in a position to comment on the validity

of the analysis where recommended technical holding times may have been breached.

Measurement Uncertainty estimates are available for most tests upon request.
